Answer:
pulmonary artery and vein are diff from usual artery and vein because
usually artery carries oxygenated blood but pulmonary artery carries deoxygenated blood(from right ventrical to lungs for purification) and
usually vein carries deoxygenated blood but pulmonary vein carries oxygenated blood(from lungs to left aurical after purification).
